Both my grandads were on my ouija board and I am 100% it was them and they told me my fionce was going to die from cancer very soon and I will be pregnant in 2 months would you say that will be true

And Carter will be re-elected President. It is foolish to believe in such child toys.
At worst, it would be demons and of course they can't tell the future, only current or past.

Aaaaaand this is why you don't play with ouija boards.
